Description

  The present invention relates to a storage staircase to which a storage function is added.

  In the case of a house used for a two-story building or the like, a staircase is provided as a means for going up from the first floor to the second floor. Here, the space below the stairs is often a dead space that is not used.

  As a technique for utilizing such a dead space, a staircase that is provided directly below the tread plate of a staircase having a side plate, a tread plate, and a kick plate and is used by being drawn forward from the plate surface portion of the kick plate. The lower drawer-type storage is disclosed (for example, refer to Patent Document 1).

JP 2009-185446 A

  However, in the technique of Patent Document 1, although the dead space under the stairs can be used as a drawer, it is necessary to provide a dedicated drawer in the stepped portion, which makes the structure complicated and expensive. Furthermore, in the technique of Patent Document 1, the function of raising and lowering the stairs is temporarily lost when the drawer is opened and closed. In addition, since storage rails and drawers are directly provided on the normal size treads and side plates, problems such as load resistance, strength, noise during lifting, and squeaking may occur.

  The present invention has been made to solve such a conventional problem, and is to provide a storage staircase having a storage function added while simplifying the structure.

  The storage staircase of the present invention is a storage staircase in which a plurality of treads are arranged at predetermined intervals in the vertical direction between side girders, and each of the plurality of treads has a front end of a predetermined tread on the upper stage of the tread. A tread part extending forward with a predetermined width from the front end of the tread, and a storage part with the rear end of the predetermined tread extending rearward with a predetermined width from the front end of the upper tread of the tread It is characterized by that.

  According to the storage staircase of the present invention, since it is a structure that only enlarges the size of the tread board, it is advantageous in terms of cost compared to the conventional storage staircase. Moreover, since it can be stored not only from the front of the stairs but also from the back of the stairs, it is possible to broaden the usage and usage.
